How many wires does the dual control switch have?

Generally, a double-link dual-control switch.

A minimum of 5 wires are required, one power cable on each side, two control wires, and then the neutral and ground wires are added. In special cases, it will be decided separately. The wiring method of the double control switch is to connect the terminal post in the middle of a double control switch to the live wire, and then connect the middle terminal post of another double control switch to the lamp head, and then connect the back and forth wires, that is to say, to connect the upper and lower two binding posts with two green wires.

The neutral wire is another contact that is directly connected to the lamp head, so that the sub-duplex double control switch is connected.

Here are some important points to note:

1) One of the lines in the double line must be directly connected to the middle and indirect end of the two double control switches;

2) Another wire in the double wire should be connected to any one of the upper and lower terminals of the switch, and a branch line should be connected to one end of the lamp in the middle indirect, and the other end of the lamp should be connected to the zero line;

3) Both switches should be connected to the live wire and the balance should be connected to any of the upper and lower terminals, but the intermediate terminals must not be connected.

In general, the switch with double opening and dual control needs to be connected to six wires. Because there are generally two sets of interfaces on the back of the double-open and double-control switch, each group has three interfaces, so the double-open and dual-control switch has a total of six interfaces, and each interface must be correctly wired before it can be used.

Five wires of the double control switch are enough, 4 return control lines are connected to the two switches, and then the main fire wire is put on the second switch in string, and the first switch is two L on the tempering line of the two lights respectively.

There must be 6 wires on the switch, but there must also be 1 neutral wire. If the neutral wire is directly connected to the lamp head, there is no need for the neutral wire.

The single-link dual-control switch generally has three binding posts, which are represented by L L1 L2 respectively, and three wires are required to complete the dual control task. Generally, the wiring mode of live wire inlet and double control out is selected, and there are also "double inlet" wiring methods.

Dual-control switches require three wires, one main line and two control wires.

One wire, one power cord is connected to switch L, and the lamp wire is connected to switch L1.

The single-gang dual-control switch requires 3 wires.

Hello, I have seen your question and am sorting out the answer, please wait a while How many wires does a single and dual control switch need?

Single-gang and dual-control switches can be used with at least 3 wires. One open and double control is two switches, each switch is three wires: a switch one live wire, two control live wires; B switch three control wires.

Extended information: The power live wire is connected to the No. 2 terminal post of the first dual-control switch and the No. 2 binding post is connected to the No. 2 terminal post of the second dual-control switch with 2 wires respectively. The No. 2 binding post of the second double-control switch is connected to the lighting fixture, and the other terminal of the lighting fixture is connected to the neutral line of the power supply.

This completes the wiring. Dual-control principle: if the two dual-control switches hit the "position" of the terminal post at the same time (or hit the position of the terminal post at the same time), the live wire is connected and the light is on; If one of the two dual-control switches is in the "through" position and the other is in the "through" position, the live wire will not be connected, and the lights will be turned off.

A dual-control switch is actually two single-pole double-throw switches connected in series before being connected to the circuit. Each SPDT switch has three terminals, one with two contacts and one knife.

Five wires are required.

On each side is a power cord and two control wires. Then add the ground and neutral wires. To put it simply, it is 2 switches L1 L2 docking, one switch L into the fire line, and the other switch L into the lamp head line, which is a single dual control, and a double dual control is 2 panels.

1. The so-called "bit", also known as "link", refers to several switch function modules on a panel. "One bit" means that there is a switch, and "two bit" means that there are two switches, which can control two electrical devices respectively.

2. The so-called "control" means that a switch selectively controls several circuits. For example, the double-control switch is represented by the letters A and B, that is, the process of switching is the process of turning on A to disconnect B, or to turn on B to disconnect A. Both lines are not turned on at the same time, nor are they disconnected at the same time.

In the family, two dual-control switches can be used to control an electrical appliance in two places through certain wiring rules, and this function is more widely used in the lighting of the living room and bedroom.

Dual-control switch, three binding posts, press the entrance line for the red, blue line, red for L blue for N, the blue line for the entrance is directly connected to the upper binding post of a dual-control switch, the middle binding post is the blue line connected to the side of the lamp, and the lower binding post is connected to the red line of the household.

The red line of the house is connected to the upper binding post of another double control switch, the middle terminal post is the red line to the other side of the electric light, and the lower binding post is connected to the blue line of the house.

A double-link dual-control switch is a panel with two dual-control switches.

The double switch is a switch panel with two sets of switches, which can control the two lights to be turned on and off respectively, and the double control switch is a switch that can realize the switch lights in different places, and it has three terminal points, one is the common end, and the other two terminals are on or off respectively.

Hello, double control switch, the pictures drawn by several people upstairs are correct.

Add two dual control wires between the two switches.

Here's how to connect. The hole marked with L in the terminal of switch A is the common end, the live wire, and the dual control wire is connected to both sides (the two holes are generally represented), and the hole marked with L in the terminal of switch B is connected to the lamp head wire, and the two sides of the double control wire are not divided into positive and negative (the two holes are generally indicated).

Three wires. Both access switch methods are three-wired.

Double-connected and dual-control switches, before wiring, figure out what the 6 wires in the junction box are.

If two switches control one light, you need to add two double control wires between the two switches A and B.

The connection method is as follows: the hole marked with L in the terminal block of switch A is the common end, the live wire, and the double control wire is connected to the L1 and L2 holes.

The hole marked with L at the terminal of switch B is connected to the lamp head wire, and the double control wire is connected to the L1 and L2 holes.

The wiring of the dual control line is not divided into positive and negative, but the common end of the switch cannot be connected wrong.

At least five wires pull the live wires through the old switch and leave two control wires as the main line for the new switch live wire as the main line and the remaining four wires as two secondary wires for the two switches.
